Solution

The correct option is B Concentration of a solute is proportional to the absorbance
Beer-Lambert law states that the concentration of a solute is proportional to the absorbance. It defines the linear relationship between absorbance and concentration of an absorbing species as
A = εdC
Where: A = Absorbance.
ε = Molar absorptivity.
d = Path length of the cuvette containing the sample.
C = Concentration of the compound in the solution.
So, the correct answer is option B.
